which circle is largest? (1 in= 2.54cm). Circle A: diameter- 8in., circle B: circumference= 20in or Circle C: radius= 13 cm
IceJOKER [234]
C. Radius = 13cm

Circumference = pi(2r)
C = 3.14(2x13cm)
C = 81.64cm x 1in/2.54cm = 32 in

Pi / 3.14<span>
Where pi is defined as the ratio of a circle’s circumference divided by the diameter of the its circle. Pi has a value which is 3.1416. This pi is a constant value expressed by the quotient of its circumference over the diameter. What type of number best describes the diameter is the pi. Hence, if we describe the diameter, diameter is the quotient of pi over the circumference of a circle by itself. It can’t change in value since for every solution and quotient of a circle each calculation gets 3.14 more or less.<span>

you deposit 10000 into a bank account. the account pays 4 annual interest compounded quarterly. find the balance after 5 years.
Ann [662]
<h3>Answer: 12,201.90 dollars</h3>

You may need to delete the comma if you are entering this result into a computer system.

=====================================================

Work Shown:

P = 10,000 = deposit

r = 0.04 = decimal form of 4% interest rate

n = 4 = we're compounding 4 times a year

t = 5 years

-------------

A = P*(1+r/n)^(n*t) .... compound interest formula

A = 10,000*(1+0.04/4)^(4*5)

A = 12,201.9003994797

A = 12,201.90

After 5 years, there is $12,201.90 in the account.

This is assuming you do not deposit any more money, and it also assumes that you don't take any money out during the 5 year timespan either.

consider the following function. f(x)=4x+7. Place the steps for finding f-1(x) in the correct order (photo)
Finger [1]

Step-by-step explanation:

f(x)=4x+7

y = 4x+7

4x = y-7

x = (y-7) /4

the correct answers are:

=> f`¹(x) = (x-7) /4 (a)

=> x - 7 = 4y (e)

=> (x-7) /4 = y (f)

=> x = 4y +7 (g)
